Product details
Overview
VS-ST180S16P0 from Vishay Semiconductors is a phase-control thyristor (SCR) in stud-mount TO-93 (TO-209AB) metal-ceramic package, rated for 200 A average on-state current at 85 °C case temperature, 1600 V repetitive peak off-state voltage (VDRM/VRRM), and 1.75 V maximum on-state voltage at 570 A peak. It features center-amplifying gate drive, hermetic sealing, and compression-bonded construction for industrial-grade thermal cycling resilience, used in high-power AC/DC motor control and regulated power supplies.
For engineers reviewing the VS-ST180S16P0 datasheet, VS-ST180S16P0 pinout, VS-ST180S16P0 application, or VS-ST180S16P0 equivalent, key selection criteria include its 100 μs typical turn-off time (tq), 1000 A/μs dI/dt rating, 500 V/μs critical dV/dt, and stud-mount mechanical interface with 3/4"-16UNF-2A threads - all critical for high-reliability phase-angle control in industrial converters.
Technical Context
This single SCR operates as a latching unidirectional switch triggered by gate current (IGT ≤ 150 mA at TJ = 25 °C), with defined holding (IH = 600 mA) and latching (IL = 1000 mA typ.) currents. Its blocking capability spans 1600–2000 V VDRM/VRRM, supporting both 50 Hz and 60 Hz line-frequency applications with validated surge ratings up to 5230 A (60 Hz, 8.3 ms).
Thermal design relies on low junction-to-case resistance (RthJC = 0.105 K/W DC), enabling high-power dissipation when mounted to heatsinks via torque-controlled stud (24.5 N·m lubricated). Gate triggering uses standardized pulse conditions: 20 V, 10 Ω, tr ≤ 1 μs, with PGM = 10 W peak and PG(AV) = 2.0 W at 50 Hz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IT(AV) | 200 A at TC = 85 °C - defines continuous DC or half-sine conduction capability under heatsink-cooled operation |
| VDRM / VRRM | 1600 V - maximum repetitive off-state voltage before breakdown; sets minimum isolation margin for 1200 V AC line applications |
| VTM | 1.75 V at Ipk = 570 A, TJ = 125 °C - determines on-state power loss (≈1 kW peak) and thermal stress during conduction |
| tq | 100 μs typical - specifies minimum commutation interval required before reapplied voltage; critical for forced-commutated inverters |
| dI/dt | 1000 A/μs - maximum rate of rising anode current the device can sustain without false triggering; governs snubber design |
| dV/dt | 500 V/μs - maximum rate of rising off-state voltage before spurious turn-on; constrains EMI filtering and layout dv/dt control |
| IGT | 150 mA max at TJ = 25 °C - gate trigger current threshold defining driver strength requirement for reliable turn-on |
Pinout & Package
VS-ST180S16P0 uses a hermetically sealed TO-93 (TO-209AB) stud-mount metal-ceramic package with 3/4"-16UNF-2A threaded stud (anode), insulated ceramic base, and two flexible leads: white-shrink insulated gate lead and red-shrink insulated auxiliary cathode lead. Mounting torque is 24.5 N·m (210 lbf·in) for lubricated threads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Stud) | Main current terminal (high-side connection) | Threaded metal stud serves as electrically active anode and primary thermal path to heatsink; requires insulating washer if heatsink is grounded |
| Cathode (Red lead) | Main current return path | Flexible insulated wire provides low-inductance cathode connection; termination must accommodate 314 A RMS current and thermal expansion |
| Gate (White lead) | Control input for turn-on initiation | Isolated gate lead accepts pulsed trigger signals; must be routed away from high-dI/dt paths to prevent false triggering |
Key Features
| Feature | Design Value |
|---|---|
| Center-amplifying gate structure | Enables uniform turn-on across large silicon area, reducing localized heating and improving surge current sharing in parallel configurations |
| Hermetic metal-ceramic enclosure | Prevents moisture ingress and contamination over lifetime, supporting >20-year field reliability in humid or chemically aggressive industrial environments |
| Compression-bonded encapsulation | Withstands ≥1000 thermal cycles between -40 °C and +125 °C without bondline degradation or parameter drift |
| Industrial-level qualification | Meets extended temperature (-40 to +125 °C), surge (5230 A @ 60 Hz), and long-term stability requirements per IEC 60747-6 |
| Stud-mount mechanical interface | Provides direct thermal conduction path and high-current mechanical anchoring; eliminates solder joint fatigue failure mode common in PCB-mounted devices |
Applications
| DC Motor Speed Control | Controlled DC Power Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-control thyristor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ST180S16P0 (Vishay) | Same family, Pb-free version with identical electrical specs and TO-93 stud package | Direct replacement for legacy VS-ST180S16P0; same mounting and thermal interface | Select when RoHS compliance is mandatory and no change in supply chain qualification is permitted |
| SKKT 180/16E (Semikron) | Higher VRRM (1600 V), same IT(AV) = 200 A, but TO-209AA package with different stud thread (M16 × 1.5) and higher RthJC = 0.12 K/W | Requires mechanical redesign for stud mounting; lower dV/dt (400 V/μs) limits use in high-noise environments | Choose when sourcing from European distributors or integrating into Semikron-based reference designs |
Compared with ST180S16P0 and SKKT 180/16E, VS-ST180S16P0 offers identical core ratings but includes Pb-free processing and optimized gate sensitivity (IGT ≤ 150 mA), making it preferable for new designs targeting global environmental compliance without sacrificing surge robustness or thermal performance.

FAQ
What is the maximum allowable case temperature for continuous operation of VS-ST180S16P0?
The VS-ST180S16P0 is rated for 200 A average on-state current at a case temperature (TC) of 85 °C. Operation above this temperature reduces allowable current per derating curves in Figure 1 of the datasheet; maximum junction temperature remains limited to +125 °C regardless of case condition. Thermal design must ensure RthC-hs ≤ 0.04 K/W with greased interface to maintain safe TJ under full load.
Does VS-ST180S16P0 support both 50 Hz and 60 Hz line frequencies?
Yes, VS-ST180S16P0 is fully rated for both 50 Hz and 60 Hz operation. Its non-repetitive surge current (ITSM) is specified as 5000 A at 50 Hz (10 ms) and 5230 A at 60 Hz (8.3 ms), and its turn-off time (tq = 100 μs typical) is validated under both frequencies with standardized test conditions including dI/dt = 20 A/μs and VR = 50 V.
What gate drive parameters are required to reliably trigger VS-ST180S16P0?
VS-ST180S16P0 requires a gate pulse with peak voltage ≤20 V, source impedance ≤10 Ω, and rise time ≤1 μs. At TJ = 25 °C, IGT ≤ 150 mA guarantees turn-on; at TJ = 125 °C, IGT drops to ≤40 mA. Recommended gate circuit uses 20 V/10 Ω for rated dI/dt applications, delivering PGM ≤ 10 W peak and PG(AV) ≤ 2.0 W at 50 Hz.
Is VS-ST180S16P0 compatible with standard TO-93 heatsink mounting hardware?
Yes, VS-ST180S16P0 uses a 3/4"-16UNF-2A threaded stud compliant with TO-209AB (TO-93) mechanical standards. Mounting torque is 24.5 N·m (210 lbf·in) for lubricated threads or 31 N·m (275 lbf·in) for dry threads. The stud diameter (8.5 mm) and flange geometry match industry-standard TO-93 heatsink clamps and insulating washers.
What is the end-of-life status of VS-ST180S16P0 and what alternatives does Vishay recommend?
Vishay has declared VS-ST180S16P0 End of Life effective December 2024. Official alternative solutions include the Pb-free ST180S16P0 (same specs, RoHS-compliant) and cross-series options like the VS-ST200S16P0 (200 A, 1600 V, improved tq = 80 μs). Customers should contact [email protected] for migration support and sample availability before EOL date.
